I've had to shelf this project for a while longer. Or rather, I've had to shelf this project again for a while longer. I was really counting on this contest to be the thing to force me to give it more time on the bench.

Sadly this last year has left me with double the amount of work and, therefore, half the amount of time to work on things like this.

The breakthrough for this project was finding some great sample code on frequency detection that I planned to use to handle the main workload.

From there, it's a matter of mapping those frequencies to specific macros/keystrokes/keycodes on the receiver side.

So, really, this entire project is yet another macro keyboard (the project of the day, it seems) but with a retro twist.
